It is pretty cool. Build quality is great! The screen is fantastic, better than my SGS2. I haven't taken any pictures yet, so no thoughts there. The phone performs really well. Apps open VERY fast and the "recent apps" feature is pretty responsive.
Better than the SGS2? Maybe. Better than the SGS3? I doubt it, but we will find out when they get them in store.
I bought an otterbox and insurance on this phone. No way I am going to risk damaging it during this test period.
One downside, no sd card slot
